This is a calculated estimate derived from the figures you entered and the factors in the configuration layer. It is not a measurement of your emissions.

    Current vs. renewable scenario

    Estimate

    Compares your current modelled emissions with the same footprint after the 5.0 kW solar array selected below displaces grid electricity. Only electricity emissions can be displaced by solar generation.

    Both figures are modelled estimates from unverified placeholder factors. The reduction is capped at your electricity emissions and assumes every generated kWh displaces grid supply at the annual average factor.

    Solar Potential

    Estimate

    A first-order screening estimate of what a rooftop or ground-mount solar array could generate, and the grid electricity emissions it could displace. Adjust any parameter to see the effect immediately. This is not a professional solar-site assessment — it includes no shading analysis, roof survey, tilt and azimuth modelling, or interconnection review.

    Capacity vs. annual generation

    Estimated annual energy yield (kWh) across system sizes, at the parameters above.

    Equations used (all outputs are estimates)

    Annual generation = capacity × sun hours/day × 365 × performance ratio = 5.0 × 4 × 365 × 0.8 = 5,840 kWh/yr

    Avoided CO2e = generation × electricity emission factor = 5,840 × 0.4 = 2,336 kg CO2e/yr

    • Sun hours, performance ratio and the emission factor are unverified placeholder assumptions unless you replace them with site-specific values.
    • The model is annual and linear: it ignores seasonal and hourly output variation, shading, roof area limits, orientation, snow, soiling and degradation over time.
    • Avoided emissions assume every generated kWh displaces grid electricity at the annual average factor — real displacement depends on when generation and demand coincide.
    These figures are modelled estimates for exploration and education only. They are not a professional solar-site assessment, engineering design, or financial projection. Consult a qualified installer for a site-specific study.

    Estimated monthly energy generation

    Estimate

    The annual estimate spread across the year using the seasonal shape held in the configuration layer — an assumed profile, not measured site data.

    Assumption: Illustrative seasonal shape for a mid-latitude northern-hemisphere site. Real profiles depend on latitude, tilt, weather and snow cover. Source: PLACEHOLDER — replace with cited published dataset.

    Renewable Transition Score

    An informal indicator we define ourselves, from 0 to 100, built only from your inputs and the modelled solar scenario. It is not an official environmental certification, rating or audit, and it cannot be compared with any external scheme.

    Early stage

    • Solar coverage of electricity use0 / 45 pts

      0% of your annual electricity use covered by the modelled array (100% earns the full 45 points).

    • Share of total footprint avoided0 / 30 pts

      Modelled scenario avoids 0.0% of your total footprint (a 40% cut earns the full 30 points).

    • Grid carbon intensity5.5 / 15 pts

      Electricity factor used: 0.4 kg CO2e/kWh (0.05 or cleaner earns the full 15 points, 0.60 or higher earns none).

    • Non-transport share of footprint10 / 10 pts

      Transport is 0% of your footprint (0% earns the full 10 points, 60% or more earns none).

    The score is a teaching aid built on unverified placeholder factors and assumed solar parameters. Changing any assumption changes the score.
    Factors currently loaded are unverified placeholders and the uncertainty band is indicative, not propagated. See Methodology for every equation and assumption behind these figures.
